7Semi EG800AK-CN LTE Cat-1 bis USB Dongle - Quectel EG800AK-CN, 10 Mbps, USB Type-A with UART Breakout, AT Command Interface for IoT, Industrial, and Embedded Development
The 7Semi EG800AK-CN LTE Cat-1 bis USB Dongle is a compact 4G LTE cellular connectivity solution built around the Quectel EG800AK-CN LTE Cat-1 bis modem in a USB Type-A dongle form factor, combining the plug-and-play convenience of a USB-connected modem with the direct UART breakout pin access required for embedded system and microcontroller-based AT command integration. The USB Type-A interface provides simultaneous modem power supply and USB communication to a connected host computer, Raspberry Pi, Linux SBC, or USB-OTG-capable embedded platform without an external power supply, while the exposed UART breakout pins covering TX, RX, VIN, and GND extend modem AT command access to ESP32, STM32, RP2040, Arduino, and other microcontroller platforms that cannot directly enumerate the USB modem interface but can communicate with the modem over a hardware UART serial connection. This dual-interface architecture makes the 7Semi USB Dongle a versatile development and deployment tool across both USB host-capable platforms requiring plug-and-play LTE access and UART-based microcontroller systems requiring direct serial AT command modem control from a conveniently packaged cellular module.
Supporting LTE-FDD bands B1, B3, B5, and B8 alongside LTE-TDD bands B34, B38, B39, B40, and B41, the EG800AK-CN modem covers the frequency band allocation of major LTE operators in India and China, providing broad carrier compatibility across both regions without band-specific modem variant selection for developers and deployment engineers operating across the two markets. Cat-1 bis delivers download speeds up to 10 Mbps and upload speeds up to 5 Mbps, positioning the dongle in the cost-effective mid-tier LTE category that provides sufficient bandwidth for IoT data streaming, telemetry uplink, OTA firmware updates, and industrial monitoring applications without the hardware cost and power premium of Cat-4 and higher modem solutions, where peak throughput headroom is not operationally required. Onboard power regulation circuitry manages the USB input voltage to the modem's required supply rails, and the included external LTE antenna connects via the U.FL and IPEX antenna connector for immediate deployment without additional antenna sourcing. Status indication LEDs provide visual network registration and power state confirmation without requiring AT command polling or serial terminal monitoring in field deployment scenarios.
